Question

我想在glsurfaceview android上录制。

private GLSurfaceView glview;
private Button start;
private Button stop;
private MediaRecorder mediaRecorder;
@Override
public void onClick(View v) {
   if ( v == start) {
        mediaRecorder = new MediaRecorder();
        mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
        mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
        mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
        mediaRecorder.setVideoSize(176, 144);
        mediaRecorder.setVideoFrameRate(20);
        mediaRecorder.setPreviewDisplay(glview.getHolder().getSurface());
        mediaRecorder.setOutputFile("/sdcard/test001111.mp4");

        try {
            mediaRecorder.prepare();
            mediaRecorder.start();    //occur exception
        } catch (IllegalStateException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

        if (v == stop) {
            if (mediaRecorder != null) {
                mediaRecorder.stop();
                mediaRecorder.release();
                mediaRecorder = null;
            }
        }
    }
}

我尝试搜索，但只在surfaceview示例上录制。

我想要GLSurfaceView

当我开始点击按钮时，发生异常。

和我的logcat
